Title: Improvements in high frequency electric apparatus
IPC: H01J25/06
Filed: 1939-11-01
Abstract: 533,939. Coupling high-frequency circuits. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 1, 1939, No. 29175. Convention date, Nov. 1, 1938. [Classes 40 (iii) and 40 (v)] In a method of coupling a short-wave generator to an amplifier modulator, antenna, &c. by a transmission line, the impedance of the line is matched to the optimum load impedance of the generator or to the input impedance of the amplifier &c. by means including a condenser serially connected between the two systems to be coupled and having a reactance approximately equal to the geometric mean of the characteristic impedance of the line and the load impedance of the generator or the input impedance of the amplifier &c. In the arrangement described, an ultra-short wave oscillator of the type described in Specification 533,500 is coupled by a concentric transmission line 70, 71 to an amplifier 55 of the type described in Specification 530,251. The line 70, 71 is coupled to the amplifier by a condenser 80 and a resonant transmission line 74, 75 is associated with the amplifier &c. to make its input impedance purely resistive; this input impedance may be 1,000 times the characteristic impedance of the line 70, 71, and the condenser 80 is given a value equal to the geometric mean of these two impedances. The resonant line 74, 75 is slightly mistuned so as to give an inductive reactance equal to the capacitive reactance of the condenser 80. Similarly, the transmission line 70, 71 is coupled by a condenser 83 to the output electrode 50 of the generator, with which is associated a resonant transmission line 81, 82 which may be a half-wave line similar to 74, 75 o:r a quarterwave line short-circuited at its end as shown. The line 81, 82 is slightly mistuned to give an inductive reactance equal to the capacitive reactance of condenser 83.

Abstract: 889,879. Electric resistances. ELETTRONICA METAL LUX S.p.A. Sept. 12, 1958, No. 29374/58. Class 37. A resistor comprises a cylindrical insulating body 11 on which are formed a pair of terminals 16, 17 having two proximate edges extending along the cylinder and separated by a gap bridged with a resistive film 21. As described, triangular terminals 16 and 17 are formed on the ceramic rod 11 by, for example, coating the entire rod with silver paste, with the exception of the gaps 18 and 19. A resistive film 21 is then deposited over the entire cylindrical surface, so that the part of this film which lies in the gaps 18 and 19 provides the resistance of the device. When a precisely controlled resistance is required, grooves 22 may be ground through the resistive material in one or both of the gaps. As an alternative embodiment, the terminals may be produced by applying the silver paste so as to define only the edges 23, 24 of the gap 18. Specification 889,878 is referred to.

[Also in Division B8] In a self-adjusting wedge unit, inclined surfaces 8 on a fixed wedge 2 engage corresponding inclined surfaces 7 on a movable wedge 1, longitudinal ribs 3 on the wedge 2 co-operating with the sides 6 of the wedge I to prevent relative lateral motion, and a compression spring 12 held between the head of a bolt 10, screwed into a lug 5 on the wedge 2, and an end plate 18 of the wedge 1, locates the wedges longitudinally and renders the unit self-adjusting. A climbing tower crane having corner posts C and lateral members B is located in an opening A in a concrete floor of a building by wedge units grouped two at each corner of the opening, Fig. 4. Two fixed wedges 2 are carried by a corner plate 14 clamped in the comer by upper and lower plates 17, 19 connected by a bolt 16, while the movable wedges 1 bear against the outer faces of a corner post C. To locate the tower of the crane, each bolt 10 is screwed down to compress the springs 12. When the load on a wedge unit is reduced, e.g. due to slewing of the crane boom, the spring 12 urges the movable wedge 1 downwardly to maintain contact with the corner post C. A nut 13 on each bolt 10 is used to withdraw the wedge 1 to release the tower crane.

Classes 39(i) and 39(iv) In a radiation measuring instrument comprising an ionization chamber and means such as an electrometric triode or tetrode which may be located within the chamber for measuring an electrical current produced as a result of ionization in the chamber, the construction of the chamber and the nature of its gaseous filling are such that the value of the current for a given amount of radiation is the same irrespective of whether the latter is beta, gamma, fast neutron or thermal neutron radiation. The chamber has a cubic capacity of between 0.1 and 30.000 c.c. and the walls, which are made for example of the material known by the Registered Trade Mark " Bakelite" or of aluminium, of a thickness between 0.01 and 5 mm. to pass the gamma and neutron radiation, may be lined either partly or completely with a compound containing hydrogen, such as paraffin, a compound containing boron, a mixture of such compounds, or a compound containing nitrogen and either cadmium or indium, for the purpose of moderating the neutrons. A window, located in the front face of the chamber, has an area of between 10 per cent and 90 per cent of the area of said face, a thickness of between 10 and 100 Á, and is made of material which will pass beta rays, such as organic material, aluminium or mica. The gas filling may comprise hydrogen, nitrogen, air, oxygen, carbon dioxide, one of the rare gases, an organic gas, gaseous boron compounds, or a mixture of such gases at a pressure of between 0.8 and 3 atmospheres. The moderating effect may be due to the wall coating or to the filling or to both.

Abstract: 868,919. Control line regulators. PACIFIC SCIENTIFIC CO. Aug. 31, 1959 [Sept. 8, 1958], No. 29702/59. Class 105. In a spring tension regulator which maintains a uniform tension in a pair of cables joining a control with a controlled surface, e.g. a rubber or elevator on an aircraft and which automatically locks against .further operation when a control force is applied to one of the cables, means are provided, when such a control force is applied, for taking up the slack produced in the untensioned cable. On the shaft 1 is mounted a hub 4 which is formed with an arm 6 adapted at its end 7 for connection by means of a link to the member being controlled and with a tubular projection 8 within which is fitted a member 9 supporting at its outer end the rocker arm 13. Also mounted for turning about the shaft 1 are two sectorshaped sheaves 19 and 191 which are connected by telescopic members 16, 17 and 161, 171 to the outer ends of the rocker arm 13. Springs 30 and 30<SP>1</SP> surrounding the telescopic members urge the sheaves 19 and 19<SP>1</SP> anti-clockwise and clockwise respectively about the shaft 1. The sheaves are also connected by arms 26 and 261 to a locking bar 24 which is urged by the spring 29 towards the shaft 1. The arcuate peripheral parts of sheaves 19, 19<SP>1</SP> are grooved to receive the cables 22 and 22<SP>1</SP> and the ball ends of these cables are retained in sockets 23, 23<SP>1</SP>. When no force is being transmitted via the regulator the cables 22 and 221 are tensioned by the action of the springs 30 and 301 and the locking arm 24 slides along the member 9 as any length increases or decreases are compensated for. When a control force is applied, e.g. to cable 22 the looking arm 24 is tilted and locks on the member 9 and the force is applied via arm 6 to the surface which is being controlled. The tendancy for cable 221 to sag due to lack of tension is opposed by spring 301 which turns sheave 19<SP>1</SP> clockwise through an angle which is limited by the length of the slot 281 formed in the arm 26<SP>1</SP> in which the pin 27<SP>1</SP> moves.
